‘Enigmatic’ footprints reveal prehistoric crocodile that walked on two legs
Ancient footprints embedded in rock in South Korea likely belonged to a prehistoric crocodile that walked on two legs, paleontologists said.
It’s the first time this gait has been found in this family of ancient crocs, which typically walked on four legs like modern-day crocodiles and alligators. The well-preserved tracks included footprints that were 18 centimeters (7 inches) to 24 centimeters (9 inches) in length, indicating a body length of up to 3 meters (10 feet.)
